Processes and apparatuses for heating process fluid in a furnace. Fuel to the furnace is either hydrocarbons or hydrogen. The fuels may be sent to different furnaces or be sent at different times to the same furnace. Furnaces that are configured to receive both types of fuels may have different exhaust paths. An exhaust path for hydrocarbon fuel flue gas includes a carbon capture process zone.

The invention relates to a method for the thermal disposal of pollutants in industrial gases, wherein, in order to generate a flame for burning the pollutants, a fuel gas and oxygen are fed into a combustion chamber (19) of a burner (1), where they are then ignited, wherein a diluent gas is fed in in order to reduce the calorific value of the gas mixture relative to the fuel gas, while the throughput of the diluent gas is regulated as a function of the composition of the industrial gas in order to adapt the gas mixture consisting of diluent gas and fuel gas. The invention also relates to a burner (1) for generating a flame (2) in a combustion chamber (19) for burning pollutants in an industrial gas, and to a waste-gas treatment device having at least one burner (1) arranged in a combustion chamber (19).

A method of monitoring a flame during gas combustion in a combustion chamber (10). A heating unit (1) has an evaluation unit, an extraction line (11) and a sensor (12). The sensor (12) is arranged in the extraction line (11) to detect thermal substance properties of the gas. Thus, it is determined if it is ambient air (B), a non-combusted fuel-air mixture (C) or particularly the hydrogen-air mixture, or a waste gas (A) generated during combustion. The sensor (12) transmits a recorded measured value to the evaluation unit. The evaluation unit uses the measured value to determine whether ambient air (B), the non-combusted fuel-air mixture (C), or waste gas (A) is flowing through the extraction line (11) and thereby determines whether the flame is burning or extinguished.

A burner and methods of using the burner. The burner produces a flame from combustion air and fuel gas. Flue gas, also produced, can be withdrawn and recycled to the burner. A cooling or condition gas, such as ambient air, may be mixed with the flue gas to reduce its temperature. The burner may also utilize a stage injection so that a portion of the produced flue gas is recycled internally.

A burner control system for improving burner performance and efficiency may determine fuel and air channel or manifold parameters. Determination of parameters may be performed with a sensor connected across the air and fuel channels. A signal from the sensor may control the parameters which in turn affect the amounts of fuel and air to the burner via a controller. Parameter control of the fuel and air in their respective channels may result in more accurate fuel and air ratio control. One or more flow restrictors in fuel and/or air bypass channels may further improve accuracy of the fuel and air ratio. The channels may be interconnected with a pressure or flow divider. Byproducts of combustion in the exhaust, temperatures of gas and air, flame quality and/or other items may be monitored and adjusted with control of the fuel and air ratio for optimum combustion in the burner.

A method and an assembly for controlling an internal combustion engine having multiple burners is provided. Combustion measurement data is collected in a burner-specific manner for each burner and assigned to a burner identification identifying the respective burner. Performance measurement data of the internal combustion engine is also collected and used to determine a performance value. A machine learning model is trained by means of the combustion measurement data, the associated burner identifications and the performance measurement data, to generate burner-specific control data which optimizes the performance value when the burners are actuated in a burner-specific manner using the control data. The control data generated by the trained machine learning model is output for the burner-specific actuation of the burners.

A method for controlling a gas turbine, having a measurement step, a prediction step which is carried out after the measurement step, and a control step which is carried out after the prediction step. In the measurement step, a state variable of a combustion within a gas turbine is measured. In the prediction step, a future combustion dynamic is predicted using the measured state variable. In the control step, a control signal is output using the prediction of the future combustion dynamic.

The disclosed technology includes a gas delivery system for controlling a target gas input rate of a fluid heating device. The system can include a sensor configured to measure a temperature of a gas flowing in a gas flow path, a modulating orifice in fluid communication with the gas flow path, and a motor in mechanical communication with the modulating orifice. The system can further include a controller configured to receive temperature data indicative of the temperature of the gas. The controller can determine a target cross-sectional area of the modulating orifice based at least in part on the target gas input rate and the temperature of the gas and, in response, output a signal to the motor to transition the modulating orifice from a first position to a second position having the target cross-sectional area.

A heating device as well as a method for the operation thereof. The heating device has an outer housing that surrounds an installation space. The components of heating device are arranged inside or on the outer housing, particularly a burner unit, a fan, a fuel valve and as an option a circulation pump. At least one of these units comprises at least one electrical and/or electronic component. On one or more of the anyway present electrical and/or electronic components at least one gas sensor is arranged on the outer housing and/or inside the installation space, particularly on a support or a circuit board of the respective electrical and/or electronic component. The at least one gas sensor is configured to create a sensor signal that describes the presence and/or concentration of at least one gas component in the atmosphere. Based thereon leakages, faults, undesired backflow, etc. can be determined. Thereupon a respective measure can be initiated, e.g. the output of a warning message and/or suction of the atmosphere by means of fan.
